  $site = Site::model()->findAll();  
  $data = CHtml::listData($site, 'id', 'type');  
  echo $form->dropDownList($siteid, 'selectedsiteid', $data, array('class' => "form-control"));

which comes after the menu bar. please somebody help me.
Thanks in advance...

Answer 1

I have solved it by using javascript, the menu butttons code is

array('label' => 'Category', 'url' => '#','linkOptions'=>array('onclick'=>'getsid()'),'visible' => !Yii::app()->user->isGuest),

and called a java script

function getsid()
{
$sid=$('#Site_selectedsiteid').val();
window.location.href = window.location.pathname.substring( 0, window.location.pathname.lastIndexOf( '/' ) + 1 ) + 'catagory?sid=' + $sid;
}
